What is Optical CXL? LLMs need massive amounts of memory. Looking ahead, this requirement will only grow. CXL is emerging as an industry standard way to enable vast pools of virtualized memory.
Here is Ron Swartzentruber, Director of Engineering from Lightelligence, to explain in 2 minutes how CXL over optics could be a game changer for data center architecture. Highlights:
- The introduction of Photowave, a product that connects devices over a low latency Optical CXL fabric, is changing the way we think of computing and data center architectures.
- The industry-backed CXL standard adds memory and cache coherency protocols to PCI Express, enabling disaggregation with much lower latency and higher bandwidth than an Ethernet-based solution.
- The Photowave product extends the reach of the CXL PCI interconnect using photonics, offering energy efficiency and dramatic savings, and supports CXL 2.0 and PCI Gen 5 connectivity.
